ELECTRPIC GONG.

SPECIFICATION forming part of Letters Patent No. 410,189, dated September 3, 1889.

Application filed January 7, 1889. $erial No. 295,712. (No model.)

To all whom it may concern.-

Be it known that I, JAMES H. PHALAN, a citizen of the United States, and a resident of Ansonia, Connecticut, have invented a new and useful Improvement in Electric Gongs, of which the following is a specification.

My invention relates to electric gongs or bells, especially such as require along stroke of the hammer.

The object of my invention is to provide devices for regulating and controlling in a satisfactory manner the bell-hammer.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a plan view of a bell provided with my improvements, and Fig. 2 is a detail elevation of a portion of the bell or gong. Fig. 3 is a detail cross-section.

Like parts are indicated by the same letter in each of the figures.

A is the bell or gong proper.

B is the hammer 011 the pivoted shank C.

D is the bed-plate, to which the parts are secured.

E are the spools of an electrical magnet, their cores being secured to the bar F, which is itself fastened to the upwardly-projecting ledge G of the plate H, secured to the bedplate D.

J is a conductor leading to the binding-post J, and thence to one of the spools in the usual manner, as indicated by the dotted lines.

J 2 is an insulated binding-post having the screw-fastened bolt J 3 therethrough.

J 4 is a binding-post, from which leads the conductor J From the bindin g-post J 2 leads a conductor J 6 to one of the spools in theusual manner. On the plate D is fixed the standard-block K, having the foot piece K and the headpiece K between which is pivoted the armature L.

L is a thumb-screw on the top of the headpiece K The armature is pivoted on the pin L To the armature is secured the flat spring N, which normally bears against the inner end of the screw-bolt J and the outer end of the flexible stop N. This stop reciprocates within the tube N, and has a collar N to engage the armature and a washer N to engage the spiral spring N the other end of which bears against the collar N". The tube N is secured by a screw-connection to the ledge G, topermit of the adjustment of the collar N with reference to the armature.

O is a screw-threaded rod passing through the sleeve 0 and ledge G and engaging the screw-threaded thumb-nut 0 whereby it may be adjusted with reference to its distance from the armature. the armature and to the end of the rod 0 is a tension-spring P.

R is a thumb-nut screw-threaded upon the rod R, which descends into the standard R and bears upon the transverse rod R This transverse rod passes through the hollow standard R and also through the lower end of the rod R, so that by turning the set-screw in either direction the transverse rod will be clamped in position. To the end of this trans verse rod, and also to one side of the armature, is secured the tension-spring S.

The use and operation of my invention are as follows: The armature, suspended as indicated in Fig. 1, is adjusted as to position by operating any or all of the adjusting devices 0 ,13 J and N or N These several adj ustments accomplish two things. They first result in suspending at the desired distance from the bell the hammer and its shank, and, as indicated by the dotted lines, this range of adjustment is very large, and by retreating the screw-bolt J it maybe made still farther. The bell-shank is held in equilibrium by the springs P and S. At the same time these adjustments result, secondly, in placing the flexible stop N at a considerable distance from the armature, so that the spring M is constantly held against the screw-bolt J so as to permit a current to pass, for example,in the direction of the arrow along conductor J binding-post J, through both spools of the magnet, along conductor J G into binding-post J along screw-threaded bolt J spring M on bed-plate D, binding-post J and out conductor J until the armature, in its movement caused by the resulting energizing of the magnet-cores, engages the elastic stop N when the spring M, which always bears with a slight pressure of the rod N, parts from the screw-bolt J and the current is broken. By this means a long stroke is given to the hammer, and the bell when operated has time to Secured to one side of a ring, rather than simply to make a clatter, as will be readily seen.

The particular devices employed could be greatly changed as to structure and position without departing from the spirit of my invention. The interior structure of the hinding-post J is the same as that of the post or device to which the rod R is secured. The rod N passes through a hole in the armature L. It will be observed that in Fig. l the up per spool of electric magnet has been removed.

I claim 1. In an electric bell or gong, the combination of apivoted armature with abell-hammer shank secured thereto, a contact-spring on one side thereof, and an elastic stop in the path of such armature and which bears against such contact-spring.

2. In an electric bell or gong, the combination of the pivoted armature with the bellhainmer shank secured thereto, a contactspring on one side thereof, and an elastic stop on the opposite side of said shank and projecting therefrom and bearing against such contact-sprin 3. In an electric bell or gong, the combination of a pi voted armature with a bell-hammer shank secured thereto, an elastic contact 011 one side and moving therewith, and an elastic stop in the path of such contact and adapted to engage the same, so that during the motion of the bell-hammer shank the contact Willnot be broken until the elasticity of' the contact and stop has been overcome.

4. In an electric hell or gong, the combination of the pivoted armature with the bellhammer shank secured thereto, and an adjustable elastic stop in the path of such armature.

5. In an electric bell or gong, the combination of the pivoted armature with the bellharnnler shank secured thereto, an elastic contact 011 one side thereof, and an adjustable elastic stop in the path of and operating against such contact.
